How to Build a Personal On-Chain Monitoring Dashboard: From Beginner to Advanced

The value of an on-chain data dashboard is to transform massive blockchain transaction records into a visual dashboard you can directly understand and even set up automatic alerts. The core path from "completely clueless" to "usable" is:First, use existing tools (Dune/Nansen) to build a simple dashboard based on existing boards, then gradually learn to create custom views using SQL and APIs.

Step 1: Understand Tool Positioning—Choose Your Battlefield

Before you start, clarify the differences between the two mainstream tools. This determines whether you "use directly" or "build yourself."

• Nansen: Track "Who" is Moving. Its core advantage is thewallet label engine, which tags over 300 million addresses with labels like "Smart Money," "Institution," and "Whale." You don't need to know who these addresses are—Nansen has already labeled them. Ideal for tracking specific entity behavior, such as "What Smart Money is buying today" or "Whether a whale is depositing to an exchange."

• Dune Analytics: Analyze "How" It Moves. It is anopen-source, community-driven SQL query platform. All dashboards are written by users in SQL. You can directly use well-established community dashboards or write your own queries to analyze on-chain activity for any protocol. Suitable for macro data analysis, such as "Uniswap trading volume trends over the past week" or "Daily active address changes for a specific L2."

Beginner Advice: Start with Dune's ready-made dashboards and Nansen's preset features to get familiar with what the data looks like before considering writing your own queries.

Step 2: Start with Ready-Made Templates (The Easiest Path)

You don't need to start from scratch. Most common monitoring needs already have dashboards built by others.

Using Dune's Ready-Made Dashboards:

1. Visit the Dune website, go to the Discover page, and search for the protocol you want to track (e.g., "Uniswap," "Aave") or analysis topic (e.g., "Arbitrum daily active users").

2. Find a data-rich, up-to-date dashboard and use it directly. You can filter time ranges, tokens, and other parameters within the dashboard.

3. If you need to modify a chart, click "Edit Query" on the chart's top right, then click the "Fork" button to copy the query to your workspace. Modify the contract address or time conditions in the SQL.

Using Nansen's Preset Features:

1. Smart Alerts: Nansen includes built-in alert templates for various scenarios, requiring no coding. For example:

   • Token Transfer: Monitor transfers from specific addresses or labels (e.g., "Smart Money Funds"), with a minimum amount threshold (e.g., $500k).

   • Exchange Flows: Monitor large token inflows and outflows to exchanges, often indicating potential buying or selling pressure.

   • Fresh Wallet Flow: Monitor new wallets acquiring tokens, which could indicate large players hiding their tracks.

2. On Nansen's Query page (supporting multiple chains like Solana), use its standardized queries or sample queries directly, modifying parameters to get data.

Step 3: Advanced Customization—When Ready-Made Dashboards Aren't Enough

Once you're familiar with the data, you can start creating your own dashboards and monitoring systems.

Creating Custom Dashboards on Dune:

1. Write Queries: Write SQL in Dune's Query Editor. For example, track daily active addresses for a specific token.

   -- Example: Count daily unique active addresses for a specific token
   SELECT
   DATE(block_time) AS date,
   COUNT(DISTINCT "from") AS active_addresses
   FROM ethereum.transactions
   WHERE "to" = 0xYOUR_CONTRACT_ADDRESS  -- Replace with your contract address
   AND block_time >= DATE('2026-01-01')
   GROUP BY 1
   ORDER BY 1 DESC

2. Create Visualizations: After running the query, select a chart type (e.g., line chart, bar chart) on the results page, configure X/Y axes, and save as a visualization component.

3. Build the Dashboard: Click "New Dashboard," name it, and save. Enter edit mode, add your visualization components or text components (supports Markdown) to the dashboard, and freely drag to adjust the layout.

Building Custom Monitoring Alerts (Combining Nansen and QuickNode):

1. Advanced Nansen Smart Alerts: Beyond templates, you can create fully custom alerts in Nansen by combining conditions like "From Custom Label," "Token," and "Min Value" to precisely filter events you care about.

2. Using QuickNode Webhooks (Fully Self-Built): If Nansen doesn't meet your needs, consider QuickNode's Webhooks service. Create a Webhook on the QuickNode dashboard, link it to a Key-Value Store list for dynamic address monitoring—add or remove addresses without restarting the Webhook. The Webhook will POST matching events in real-time to your specified server URL.

Step 4: Verification Methods—Confirm Data "Health"

After setting up the monitoring dashboard, verify data authenticity to avoid being misled by false information.

• Verify Data Sources of Ready-Made Dashboards: On a Dune dashboard, click any chart to view its SQL code, confirming it queries the correct contract address and table. Be wary of using unverified or "black-box" data from unknown sources.

• Check Nansen's Label Logic: Nansen's "Smart Money" label is based on historical profitability and does not guarantee future profits. For critical decisions, cross-verify with multiple data sources (e.g., examining specific address transaction histories).

• Beware of "Noise" Signals: Nansen's "Fresh Wallet Flow" signal could be normal new user entry or large players hiding operations. Judge based on multiple dimensions like amount and frequency.
